Coarse cut. Removes lippage, deep scratches and the damaged surface layer.
Your stone does not need replacing. It needs cutting back and bringing up again.
Marble, limestone, terrazzo, sandstone and engineered stone, restored in place. Etching, staining and wear are removed from the surface, not covered over. Most benchtops are done in a day.

Same surface, same camera.
Each of these is one photograph of one of our jobs, split down the middle. Drag the handle.
Coarse to fine. No stage skipped.
Stone is brought back by working through the grits in order. Skip one and the finish shows it.

Flattening. The floor becomes one plane.

Honing begins. Cutting marks disappear; the stone reads matte.
800
Satin. Where many honed finishes stop.
1500
Clarity returns. The veining sharpens.
3000
Reflection. A soft gloss with depth.
8500
Mirror. The finish a showroom slab has.
A worn floor might start at 50 grit and finish at 8500. A lightly etched benchtop might only need the last three. The assessment decides where to start, and that is most of what determines the price.
The tiles show one photograph of our own black marble, softened by degrees to show how the finish reads at each stage.
What we restore.
All twelve servicesMarble floor polishing
Diamond-cut back through the grits and brought up to a true reflective finish, not a topical shine that wears off in a season.
Marble benchtop restoration
Etching from citrus, wine and bench spray is dissolved stone, not a stain on top. It is cut back and re-polished in place, usually in a day, with no removal.
Marble bathroom restoration
Vanities, shower floors and walls get the wrong cleaners for years. We strip the haze, correct the etching and reseal so the room reads as new again.
Etch and stain removal
Stains sit in the stone and are drawn out with a poultice. Etches are stone that has been dissolved and are cut back. Getting the diagnosis right is most of the job.
Anti-etch protection film
A clear protective film bonded to a freshly restored benchtop. It takes the acid, the heat and the knife so the marble underneath does not. The one product that genuinely stops etching.
Stone cleaning and sealing
Deep clean with the right chemistry for the stone, then an impregnating sealer that goes into the pores rather than sitting on top. Sealing slows staining; it does not stop etching, and we say so.

The one product that actually stops etching.
Sealers slow staining. They do nothing for etching, and most of the market will not tell you that. A clear protective film bonded to a freshly restored benchtop takes the acid, the heat and the knife instead of the marble.
It suits marble kitchens that etch weekly, honed stone that shows every ring, and rentals with heavy use. Applied after restoration so the surface underneath is right first.
Is it a stain, or an etch?
Most calls we get describe an etch as a stain. They are different problems with different fixes, and getting it right first decides the price. Two questions.
An etch is stone that has been dissolved. A stain is something that has soaked in. A cleaner can shift the second, never the first.

"I am so so happy that I found Grand Stone Restorations - I had a very odd chip in my brand new engineered stone. So many companies said they could not do it and wouldn’t even bother to come and look at it.. 2 failed attempts were also made by the original company we bought the stone from. Grand Stone came in and fixed it all so well, can’t even notice the issue now and I can sleep at night lol! Can’t explain how happy I am. Will definitely use them again!"

Stone we work on.
MarbleCalcium carbonate. Beautiful, and dissolved by anything acidic, which is why it etches and why it can always be brought back. Honed or polished, floors, benchtops, bathrooms.LimestoneSofter and more porous than marble, so it stains faster and wears in the walkways. Restored with a lighter hand and sealed more often.TravertineNatural voids that fill with dirt and fail over time. Cleaned, re-filled where the fill has dropped out, honed and sealed.TerrazzoMarble chips in a cement or resin matrix. Ground flat, then polished through the grits like marble. Common in older Sydney apartment lobbies and worth keeping.SandstoneSydney's own stone. Soft, porous, prone to algae and salt. Cleaned without stripping it and sealed for the exposure it lives in.GraniteIgneous, hard, and still stains through the polish. Oil marks drawn out, surface re-polished, sealed with a product that suits its density.Engineered stoneQuartz in resin: Caesarstone, Smartstone, Quantum. Repairable and polishable within limits; heat damage to the resin is the one thing that cannot be undone.Corian and solid surfaceAcrylic solid surface. Scratches, burns and dulling are sanded out and the finish restored to matte, satin or gloss.
Where we work.
Based in Rose Bay. Most of our work is across the eastern suburbs, lower north shore and northern beaches, and we travel across Sydney.
